Invasive pest species have potential to rapidly established and spread in a new area cause major crop loss and can adversely affect food security. The spread of Invasive pest species is now recognized as one of the greatest threats to the biodiversity and economic well-being of the country. There are 23 different invasive insect pests recorded in India. Strict implementation of import regulations and international cooperation in trade and commerce, early detection and taxonomic identification at the entry points will make India secure from such invasive species. There is a need for interdisciplinary coordinated work among scientists, in identifying invaded organisms and in assessing their ecological problems, environmental concerns in different ecosystems, economic damage and sustainable management by prevention, eradication and control.
